Intra- and inter-specific predations of lady beetles were studied in spring alfalfa fields. All of the egg predations were sibling cannibalisms. Besides egg cannibalisms, pupal and prepupal predations were observed and these included intra-and inter-specific predations. In pupal and prepupal predations, those most abundant were ones by the larvae of Harmonia axyridis (PALLAS), which attacked the pupae or prepupae of Coccinella septempunctata brukii MULSANT. The cause of the inter-specific predations between H. axyridis and C. septempunctata bruckii seemed to be the time lag of the oviposition of H. axyridis and the lack of aphids.
